Abstract: This study aimed to evaluate dental implant outcomes and to identify risk factors associated with implant failure over 12 years via dental records of patients attending an educational institution. Dental records of 202 patients receiving 774 dental implants from 2002 to 2014 were analyzed by adopting a more reliable statistical method to evaluate risk factors with patients as the unit [generalized estimating equation (GEE)]. Information regarding patient age at implantation, sex, use of tobacco, and history of… Show more

“…Multiple studies have reported that bone augmentation procedure for implants was not shown favorable outcomes due to the high rate of postoperative complications and risk factors . However, we found that bone augmentation procedure was more beneficial at the single missing tooth area in this study.…”

“…Multiple studies have reported that bone augmentation procedure for implants was not shown favorable outcomes due to the high rate of postoperative complications and risk factors. [37][38][39] However, we found that bone augmentation procedure was more beneficial at the single missing tooth area in this study. Based on this outcome, we speculate that bone augmentation procedure screw loosening included: the implant-abutment connection, cantilevers, the type of restoration and para-functional habits.…”

“…Previous studies on implant failure/survival frequently report early and late implant failure (Borba, Deluiz, Lourenço, Oliveira, & Tannure, ; Ekfeldt et al, ; Esposito, Hirsch, Lekholm, & Thomsen, ; Han, Kim, & Han, ; Noda et al, ). We have opted to focus on early failure, since it is more related to the biological capacity of the bone to achieve osseointegration; late implant failure, on the other hand, is thought to result from chronic bacterial infection, so‐called “peri‐implantitis,” or overload, due to the load‐bearing capacity of the surrounding bone (Esposito, Thomsen, Ericson, Sennerby, & Lekholm, ).…”

“…There is another aspect to this problem which is related to the maintenance phase. In the next section, these aspects of the study have been elaborated as the general causes of the failure, where all the factors from the implant design and manufacturing process, to properly placement, and from the post-surgery to long-term survival are covered [6].…”

“…Implant-related risks: Implant-related risks mainly originate from the implant design parameters such as dimensions, aspect-ratio (length/diameter), material properties, safety factor and material roughness [6]. In addition, the manufacturing process, packing, storage, and providing adequate information to prevent misuse are also important stages before the surgical process.…”
